Specification of Letters Patent.

Patented. June 16, 1908.

Application filed September 12, 1907. Serial No. 392,421.

citizen of the United States, residing in Hartford, in the-county ofHartford and State of Connecticut, have invented certain new and usefulImprovements in Type- Writing Machines, of which the following is aspecification.

This invention relates to paper-severing attachments for typewritingmachines, and the object of the invention is to provide inexpensive,simplified and improved means that may be readily applied to existingmachines for cutting or severing sheets from a paper web.

A cutting-blade is secured at its ends to brackets or plates which areadjustably mounted upon the laten-frame ends, the blade lying along anin front of the platen.

Either end of the blade may be adjusted independently of the other endtowards or away from the platen, so that the blade may be readily andacc'uratelypositioned and do effective work.

In the accompanying drawings, Figure 1 is a top view of a typewriterplaten frame with' my improved device applied thereto. Fig. 2 is asectional end view of Fig. 1, and shows the paper web feeding around theplaten.

Fig. 3 1s a perspective view of the blade and brackets,

The platen l is rotatably mounted in the platenrame ends 2, connected bya paper-' table 3, all of the construction usual in the well knownUnderwood typewriter. A bracket or late 4, preferably of sheet metal,,is mounte upon each end 2 of the platen frame,-and arms 5 extendinwardly toward the platen, and downwardly inside of the platen frameends, as at 6. Secured by screws 6 to the downwardly extending parts 6are rigid arms 7. A cutting-blade 8 of some suitable hardened metal issecured at close to the platen.

each end by means of rivets 9 to the arms 7. The blade lies between the)lates 4, in front of the platen, and is incline to the latter.

The plates 4 are provided with slotslO, through which pass screws 11 forsecuring them to the platen-frame ends 2, and permit shifting of thesaid plates 4 backwardly and forwardly, together with the cutting-blade8, towards and away. from the platen, thus permitting of the insertionof a sheet or sheets of paper of different thickness between the blade 9and the platen 1. The plates 4 are shiftable one independently of theother.

The paper 14 passes from a roll 13 around the laten and up between thesame and the cuttmg-blade. When a relatively thin paper is being usedthe cutting-blade 8 is set quite However, shouldit be desired to use athicker sheet of paper, or a number of sheets of paper, the blade is setoutwardly or away from the platen by loosen ing the screws 11 andshifting the plates forwardly. The blade is set above the place'wherethe types 16 strike the platen.

Having thus described my invention, I claim: v

An attachment for the platen frames of typewriting machines,.comprisinga pair of brackets having slots for adjustable connection to the ends ofthe platen frame, each bracket having an arm to extend down i111 frontof the platen, and a cutting blade to-ex- JOHN HUTCHINSON.
